Summaries for Fructosuria, Essential

OMIM : 58 Essential fructosuria is a benign, asymptomatic defect of intermediary metabolism characterized by the intermittent appearance of fructose in the urine (summary by Bonthron et al., 1994). (229800)

MalaCards based summary : Fructosuria, Essential, also known as fructosuria, is related to fructose intolerance, hereditary and hepatocellular carcinoma. An important gene associated with Fructosuria, Essential is KHK (Ketohexokinase). Affiliated tissues include liver, testes and kidney, and related phenotypes are impairment of fructose metabolism and Strongly decreased CFP-tsO45G cell surface transport
